Implantable cardiac device with dyspnea measurement

Cardiac monitoring and / or stimulation methods and systems employing dyspnea measurement. An implantable cardiac device may sense transthoracic impedance and determine a patient activity level. An index indicative of pulmonary function is implantably computed to detect an episode of dyspnea based on a change, trend, and / or value exceeding a threshold at a determined patient activity level. Trending one or more pulmonary function index values may be done to determine a patient's pulmonary function index profile, which may be used to adapt a cardiac therapy. A physician may be automatically alerted in response to a pulmonary function index value and / or a trend of the patient's pulmonary index being beyond a threshold. Computed pulmonary function index values and their associated patient's activity levels may be stored periodically in a memory and / or transmitted to a patient-external device.

Flow control adapter for performing spirometry and pulmonary function testing

InactiveUS20100031964A1Increase pressureImproving inspiratory lung functionTracheal tubesMedical devicesForced expiratory vital capacityRespiratory care
A breathing circuit for a tracheostomized patient provides respiratory care and pulmonary function testing. The breathing circuit includes a flow control adapter that directs an inspiratory flow of air and an expiratory flow of air. The flow control adapter includes a subject port for coupling to a tracheostomy tube, an inspiratory port for coupling to an incentive spirometer, and an expiratory port. The flow control adapter further includes an adapter body and a one-way valve. The adapter body is configured to define an inspiratory fluid flow path between the inspiratory port and the subject port and to define an expiratory fluid flow path between the subject port and the expiratory port. The one-way valve substantially prevents air that flows generally along the inspiratory fluid flow path from flowing through the expiratory port during inspiration and allows air flowing generally along the expiratory fluid flow path to flow through the expiratory port during expiration.
